Triangle abc is an isosceles triangle in which angle b = angle c and l and m are points on ab and ac respectively such that lm parallel to bc. If angle a = 50 degree find angle lmc
Answers
Answer:
∵ ABC is an isosceles triangle
∵ m∠b = m∠c
∴ m∠b and m∠c = 180 - m∠a/2
= 180 - 50/2
= 130 /2
= 65°
∵ ∠c and ∠AMI are corresponding angles
∵ m∠AMl = m∠c = 65° (1)
From (1)
∵ ∠AMC is striaght angle
∴ m∠IMC = 180 - m∠AMI
m∠IMC = 180 - 65
m∠IMC = 115°
Answer = 115°

Find the equation (in terms of x) of the line through the points (-2,4) and (2,0)
y =
Answers
Answer:
y = - x + 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 2, 4 ) and (x₂, y₂ ) = (2, 0 )
m = [tex]\frac{0-4}{2-(-2)}[/tex] = [tex]\frac{-4}{2+2}[/tex] = [tex]\frac{-4}{4}[/tex] = - 1 , then
y = - x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (2, 0 )
0 = - 2 + c ⇒ c = 0 + 2 = 2
y = - x + 2 ← equation of line

6 Ella is a salesperson for a cosmetics company. She is paid $500 per week and a commission of 3% on sales in excess of $800.
What does Ella earn in a week in which she makes sales of $600?
Answers
The total amount that Ella earned in a week in which she made sales of $600 is; $500
How to solve Algebra Word problems?The parameters given about Ella who is a salesperson are;
Amount paid per week = $500
Commission on sales exceeding $800 = 3%
Total sales for the week = $600
From the parameters above, we see that she didn't make sales exceeding the commission limit of $800 and as such she didn't earn any extra commission.
Therefore her weekly pay was still $500

Given the expression [tex]x^2-10x+P=(x-A)(x-B)[/tex]
To get the value of P, we will use the completing the square method;

Find the lower quartile.
Answers
Answer:
-3, -3, 1, 2, | 2, 8, 12, 14
Lower quartile is negative 1
Because the middle number is the median because there is an odd set of numbers.
To find the quartile you have to arrange the numbers from lowest to highest.
When you find middle number you have to find the half of the lower half of the middle, which you will solve the lower quartile. Since there are even numbers you add the two middle numbers and divide it by 2. And you'll get the answer hope that helped

(b) The perimeter of a rectangular pool is 352 m.
If the length of the pool is 97 m, what is its width?
width of the pool: Im
Answers
Answer:
A) Length = 94 m
B) Width = 79 m
Step-by-step explanation:
A)
The area of a parking lot is 7802 m²
Area = length x width
7802 = length x 83
length = 7802 ÷ 83
length = 94 m
b)
The perimeter of a pool is 353 m
Perimeter = 2(length + width)
352 = 2(97 + width)
352 = 194 + 2width
2width = 352 - 194
2width = 158
width = 158/2
width = 79 m

Step-by-step explanation:
David is making rice for his guests based on a recipe that requires rice, water, and a special blend of spice, where the rice-to-spice ratio is 15:1. He currently has 40 grams of the spice blend, and he can go buy more if necessary. He wants to make 10 servings, where each serving has 75 grams of rice. Overall, David spends 4.50 dollars on rice.
What is the price of rice per gram?
Answers
Answer:
The price of rice per gram is 0.006$
Step-by-step explanation:
I. David wants to make 10 servings,
each require 75 g of rice and 5 spice. When ratio is 15:1
If rice : spice = 75 : x
15x = 75
x = 5
=> 5 * 15 : 1 * 5
= 75 : 5
So rice : spice is 75 : 5
II. When 1 serving require 75 : 5
So 10 servings is 10 * 75 : 5 * 10
= 750 : 50
So he must has 750 grams rice and 50 grams spice.
III. He must buy spice and rice which..
a) He has 40 grams spice, he'll buy for 10 grams spice.
b) He has no rice, he'll buy for 750 grams rice.
But the question only ask for price of rice which he spend 4.5$
= [tex]\frac{4.5}{750}[/tex]
= 0.006$
In 1 gram of rice he spend 0.006$
If 750 grams of rice, he'll spend 750 * 0.006$ = 4.5$ => true
That makes 0.006$ is the right answer.
Hope that help :)

Answer:
g = 8
Step-by-step explanation:
slope formula: (y2-y1)/(x2-x1)
-1 = (-6 -7) / (g +5)
-1= -13/x + 5
-1(x+5)= -13
-x - 5 = -13
-x = -8
x = 8
